Abstract
Over the years, the prcscncc of ncnlatological problems has gradually become more and more apparent, especially in developed nations. This trend is gaining 'momentum in developing' countries as well. It is now known that ncrnatode diseases take their toll in crop production all over the world. A recent survcy indicated that nlonetary losses due to discascs causcd by ncmatodc on a worldwide basis exceed $ 100 billion annually (Sasser and Freckmon, 1987). Though extensive in occurrence, discascs caused by nematodes Icad to great loss in tropical crop production. The 'rcasons for this arc probably many ' and diverse; ~avous;~bsloci l tcmperaturcs for nematode activity and dcvclopment during most parts of the year, longer growing seasons, cultivation of susccptiblc crops continuously year after ycar, occurrcncc of many d;jmaging spccics in thebtropics,, and lack of general awareness about these diseascs are some of thc rcasons for most of the damage. In somc crops, such as banana. coconut, and vcgctablcs. the damagc is usually spectacular, wllile in pulses, oilseeds, and Inany other crops in dryland agriculture, the damagc is less dramatic, but surc and cun~ulativc. resulting in reduced crop productivity. Crop yields in the drylands arc as sucll poor due to a lack of soil moisture and nutrients. Tlic prescncc of insect pcsts, nematodes, and other discascs further reduce the potential yields.
